A young boy was dragged off his bike and beaten up in Ashtead in a "nasty and unprovoked attack".

Police said the 11-year-old was assaulted when playing with a friend in Ashtead Recreation Ground at around 5.45pm on Sunday (August 9).

Two older boys, both believed to be in their mid-teens and with "London accents", began verbally abusing the youngsters who tried to flee on their bikes.

Police said the victim was pulled to the ground and attacked, suffering bruising to his face and shoulders.

The first suspect is described as being white, around 13-years-old, approximately 4ft 11in, of a chubby build and having light brown hair which is shaved on one side and brushed over on the other. It is believed that he was wearing a white top and white tracksuit bottoms.

The second suspect is described as being white, around 14-years-old, approximately 5ft 5in of a slim build and having black hair wearing a white polo shirt with grey panels.

“What makes this incident even worse is that it was the first time the boy had been to the park without an adult.

"Had he not been wearing a cycle helmet his injuries could have been much more serious.

“Surrey Police will not tolerate this kind of behaviour and people of any age should be able to enjoy their local park safely.

“I would like to reassure the local residents that we are doing everything possible to try and locate those responsible - I would urge anyone who saw anything or has any information to do the right thing and come forward.”
